Vehicle antenna for mobile services

Abstract

A pole-type vehicle antenna is provided that is mounted to a vehicle for the purpose of mobile services. In the vehicle antenna, a new type antenna for mobile services that substitutes for an antenna pole in a breakdown of the antenna pole is implemented by providing a thin film type preliminary antenna that performs antenna functions for mobile services inside an antenna case. Therefore, when the antenna is broken, a driver does not feel inconvenient in using mobile services.

What is claimed is:  
     
         1 . A vehicle antenna, comprising:
 an antenna case having a printed circuit board (PCB) built therein;   an antenna pole connected to a connector of the antenna case   an antenna wire mounted inside the antenna pole and connected to the PCB; and   a preliminary antenna mounted inside the antenna case to transmit and receive frequency signals.   
     
     
         2 . The vehicle antenna of  claim 1 , wherein the preliminary antenna is connected to the PCB by being connected to the connector. 
     
     
         3 . The vehicle antenna of  claim 1 , wherein the preliminary antenna is formed in the shape of a thin film forming a predetermined pattern, and the preliminary antenna includes:
 a main body that forms a predetermined pattern as one band-shaped member that repetitively follows lateral and longitudinal paths in sequence; and   a connection piece connected to the connector by being extended from one side of the main body.   
     
     
         4 . The vehicle antenna of  claim 3 , wherein the preliminary antenna is a single piece mounted inside the antenna case. 
     
     
         5 . The vehicle antenna of  claim 3 , wherein the preliminary antenna is a single piece directly printed on an inner surface of the cover of the antenna case.
